The arithmetic population density of a country does not take into account the size and topography of the country. It simply calculates the number of people per unit area, without considering the physical features of the land. This means that the arithmetic population density of a country can be misleading, as it does not provide a complete picture of the population distribution or density. For example, a country with a large area and a relatively low population may have the same arithmetic population density as a country with a smaller area and a higher population, even though the actual population distribution and density may be very different in the two countries.
